The sum of the first and second sides of the triangle is 37 cm, the second and third sides are 41 cm, the first and third sides are 32 cm. What is the perimeter of the triangle? What is the length of the second side?
Find the total sum of the indicated pairs of sides of the triangle.
37 + 41 + 32 = 110 cm.
Since we counted the values of each side of the figure twice, in order to determine the perimeter of the triangle, we divide the resulting sum by 2.
Will be:
110/2 = 55 cm.
To find the length of the second side of the triangle, subtract the sum of the first and third sides of the figure from its perimeter.
As a result, we get:
55 – 32 = 23 cm.
Answer: Perimeter 55 cm, third side length 23 cm.
